LinkedIn.com is the most popular social networking website for posting jobs, with 77 percent of openings shared there, according to Bullhorn Inc.’s 2012 Bullhorn Reach Rankings Report: An Inside Look at Social Recruiting in the USA.

Twitter comes in second with 54 percent, followed by Facebook at 25 percent.

The Northeast region is the most active in social recruiting, while the South is slightly trailing behind.

The data came from the Bullhorn Reach user network of more than 77,500 recruiters. The goal of the report is to provide insight into which social platforms are leveraged the most to recruit candidates across various U.S. regions and industries.

The top 10 most active states for posting jobs on social media include:

Maine

New Hampshire

Mississippi

Oklahoma

Massachusetts

Alabama

Connecticut

Oregon

Ohio

Rhode Island

Florida ranked 32rd overall. At the bottom of the list were Montana, Nevada and Arkansas.

In the South, the restaurant industry is the most commonly posted industry for all three of the social networks, according to the report.

Art Papas, president and CEO of Bullhorn, said the majority of jobs are posted to at least two channels, which reinforces the notion that social networking should never be overlooked in any candidate’s job search.

“We designed these reports to be a resource for recruiters and job seekers alike so they can determine the best ways to find talent and jobs based on their industries and geographies,” he said.
